Never upgrade with MTN rather cancel and save yourself the nightmare!

If I could give MTN zero stars I would! After a lengthy battle to upgrade my phone due the 'new system', I eventually upgraded my phone. I was ensured by Mothusi Moremedi at the branch in MTN branch in Greenstone Mall that everything is sorted out and that I have upgraded in the 22nd month so there is no early upgrade fee. He ensured me that there were no additional charges even after I asked him. One month later, i get charged an additional R800 for an early upgrade fee! MTN did not send me an invoice for this but casually continued to debit my account. I am still not receiving MTN invoices, but they continue to debit my account. After querying this on Hellopeter a while back, I get a message response from MTN that this was an early upgrade fee and that I should contact Mothusi. I contacted Mothusi in March/April, to this day, I have not heard from him. To make matters worse, my ITC record shows that my MTN account has been closed since I upgraded in March. I have contacted MTN on this and as usually they don't know why my account appears to be closed. Please do not reply tho this with a message MTN, I would like a phone call from you regarding this issue as your messages are never sufficient and don't resolve the issues at hand which seem to be getting worse as the days go on!
